If your having trouble against the 206 180 then i think you need to get the car looked at, get it hooked up to vag com and /or put on a rolling road. Dont take this as having a go but a healthy highline (OBDII) with your mods should be close to 190bhp. And pretty much the only cars bar the M3 which should give to a hard time are the LCR and CTR.
